Barone is charged with shooting John Sumpter IV outside Club Pink, a Munhall strip club.

Barone's defense attorney, Kevin Abramovitz, and prosecutors were ready to begin Barone's hearing when they learned that a key witness was afraid that if he told the truth, he, too, would face charges.

"I don't know a whole lot about the witness. What I do know is that this issue involved whether or not he has a Fifth Amendment privilege to not testify so he does not incriminate himself," Abramovitz said.

Abramovitz said that the judge granted that witness partial Fifth Amendment privileges, allowing him to only answer certain questions about the killing.

Police said the incident started with a fight and ended with shots fired at Sumpter, who was sitting in his car outside the club shortly before 4 a.m. on March 3.

Patrol officers said they saw a muzzle flash from a gun and went to the scene, where they saw a black car speeding away. They caught up with the vehicle on Ravine Street, and they said surveillance video helped them identify Barone, a 23-year-old local man.

According to the criminal complaint, Barone was at the club with friends. Police said one of Barone's friends told investigators he saw Barone fire his gun just before he, Barone and another man sped away from the scene.

In light of the witness invoking his Fifth Amendment right, Abramovitz asked the judge for a postponement, to better prepare for the witness against his client.
